There is no risk of stress cracking due to the various molding requirements of the conductive parts and the electrical requirements at the time of use. Copper conductive surface is coated with tin alloy, can guarantee good contact performance and smaller contact resistance. Tin alloy coating in addition to good electrical properties, but also has good corrosion resistance. Tin alloy surface treatment protects solder joints for printed circuit board terminals and connectors. In order to increase the wear resistance of the connector, the tin alloy is also used in this section. This treatment also maintains long- Solderability.
In order to meet the actual requirements of different products, according to the specific application of different materials. Nylon 6.6 is the preferred insulating material for the terminals of the terminals and connectors, and it is also recognized by almost any international testing organization. Because it has excellent resistance to leakage current breakdown, according to IEC112 standard to achieve CTI 600, which can reduce the air and leakage current crawling distance, it has been used as a general terminal material. Nylon 6.6 is resilient, rigid and resistant to corrosion of most chemical reagents and is classified as extinguished in accordance with UL94 V-O or (V-2). The modified nylon 6.6 does not contain halogen, fluorocarbons, chlorocarbons, silicones, asbestos, cadmium and formaldehyde, so all the insulating materials used in the general wiring terminals are free of toxic ingredients.
Spring gripping material
All of the clamping springs used in the Euro terminal are made of high quality, carefully selected, reliable nickel chrome spring steel CrNi. It has high tensile strength and high corrosion resistance as evidenced by years of practical experience. It is resistant to marine salt mist, urban exhaust and industrial gases such as sulfur dioxide and hydrogen sulfide. At normal temperatures of 22 ° C, it is resistant to concentrations of up to 30% saline solution and 30% dilute phosphoric acid.
